Corner areas, in particular at a right angle, are preferred because they can reach up to two edges of the motor vehicle door 10 and thus in the region of a door hinge 14 (Fig. 1 top left) or a door lock 16 (not shown) can reach. Fer ⁇ ner are for such applications triangular (Fig. 1 bottom left) or semi-elliptical (Fig. 1 top right) or semi-round reinforcing elements 1 applicable.
- For comparatively centrally mounted reinforcing elements 1 are rectangular shapes, possibly with rounded corners, preferred (Fig. 1 center). In a free corner region of the motor vehicle door 10 is preferably no reinforcing element. 1
- the reinforcing element 1 ie the first material layer 100 (Stein ⁇ layer 100), the second material layer 200, 210 (metal ⁇ layer 200 or coating 210) and the connection layer 150 are representative of all exporting ⁇ at this point approximately of the present invention referred to, ie, they can also be transferred from the subsequently described invention shown SEN reinforcing elements 1 and the insulating elements according to the invention. 1 Ie. this gain 1
- Dämmimplantation 1 are constructed as the above reinforcing elements of the motor vehicle door 10, wherein in them the fastening ⁇ supply layer 300 is missing, see Figs. 4 and 5.
- FIGS. 6 and 7 now show further developments of the reinforce- Substandard 1 and the insulation element 1.
- an adhesive 310 in particular a Haftkleb ⁇ material layer 310, which by a cover 312 or an intermediate belt 312 may be till ⁇ covers and an intermediate layer 312 (Fig. 7).
- an adhesive element 2 or tape 2 the z. B. may be formed as a tape 2 or tape element.
- Such an element 2 is universally applicable and can, of course, depending on a thickness, individually cut to size.
- An essential feature of the reinforcement 1, 2 or Dämmele ⁇ ment 1, 2 - in addition to the combination of metal (possibly as a substrate, such as the motor vehicle door in Fig.
- the stone layer 100 and / or the metal layer 200 may also have other constituents, so that these work ⁇ material layers 100, 200 in the inventive reinforcing 1, 2 or Dämmelement 1, 2 itself z.
- the reinforcing 1, 2 or Dämmelement 1, 2 have a variety of other embodiments.
- the sequence of previously known and other layers is almost arbitrary. It is per ⁇ but the one hand, preferred that the stone layer 100, the metal tall slaughter on one side, which must be an outer side not necessarily has 200 or the coating 210th ⁇ other hand, it is preferred that the stone layer immediately adjacent thereto has a metal layer 100 200th
- a plurality of stone 100 and metal layers 200 may alternate, wherein a free side of a stone layer 100 may have a coating 210.
- the gain 1, 2 and insulation element 1, 2 have a metal foam layer ( ⁇ represents Darge not in the drawing).
- the metal foam layer may preferably have a ⁇ miniumschaum aluminum and integral with the metal layer be made 200th For this purpose, a part of a Me ⁇ tall slaughter is foamed, wherein a non-foamed Ab ⁇ section, the metal layer 200 provides.
- the metal foam ⁇ layer increases the possible energy absorption of the composite mate ⁇ rials 1, 2 essential since it tung through the foam-like Gestal- how can affect a crumple zone. While the overall weight of the influential metal foam layer does not fall significantly in ⁇ , providing the metal foam layer of the invention may cause the impact strength and the absorption of shear forces is improved.
- the composite material 1, 2 may have a ring mesh ⁇ layer (not shown in the drawing).
- the Ring mesh layer may preferably comprise a plastic mesh, for example of an epoxy resin, which may have a glass fiber ⁇ reinforcement.
- the ring mesh layer substantially enhances stability of the reinforcing element 1, 2 or insulating element 1, 2, while the weight influence of the ring mesh layer is hardly noticed.
- the composite material 1, 2 by means of a fabric (also not shown in the drawing), in particular a textile fabric to be reinforced.
- the tissue may be arranged in the connecting layer 150, which is preferably in the form of an adhesive layer 150.
- a textile fabric for example, a Twintex ® or a fabric of the type Atlas 1: 1 and 1: 4 in the Ausgar ⁇ tion with carbon, glass and / or aramid fibers are used.
- a fabric reinforcement can be achieved in that the textile fabric is used as knitted fabric, knitted fabric, scrim or Ge ⁇ lichen.
- a liquid can be infiltrated into the rock, ie the stone layer 100, in order to change its mechanical and / or chemical properties. For example, it can be achieved by the infiltration of a liquid that the stone layer 100 has a higher mechanical strength.
- a FLÜS ⁇ stechnik with two components such.
- the liquid can z. B. be applied to the stone layer 100 after a thin grinding process.
- the application can z. B. with the help of a toothed spatula, a brush or a cloth.
- the stone layer 100 may have a temperature above the room temperature, the z. B. in the range between 40 to 70 ° C, in particular between 50 and 60 ° C, whereby the application and infiltration is supported. Furthermore, can be used the infiltration of liquid to protect the adhesive layer 150 against environmental in ⁇ rivers.
- This z. B. the liquid applied to that side of the stone layer 100 on which the adhesive is applied.
- a water-repellent liquid is used, which preferably also prevents leakage of a liquid to the adhesive layer 150. In this manner is established in the stone layer 100 with a liquid at ⁇ gereicherte barrier layer (not shown in the drawing).
- cooling liquid for the grinding process be applied to the stone layer 100.
- This z For example, a mixture of water and oil is used. After the thin processing the stone layer 100 is completely dry to prevent a one ⁇ infiltrate the coolant. If this is not achieved, there is the danger that the cooling liquid attacks the adhesive layer 150 and can thereby reduce the adhesive force.
- the stone layer 100 on the adhesive side is pretreated with a liquid prior to bonding (or even before sanding).
- the liquid seeps into the rock and forms a
- the adhesive 300 or the pressure-sensitive adhesive 300 or a coating 210 are applied. It is also possible to provide the side of the stone layer 100 with the barrier ⁇ layer on which the brick layer 100 is PHnge ⁇ ground. In this case, the barrier layer then prevents the penetration of cooling liquid into the stone layer 100, of course only as long as the barrier layer is still present.
- a liquid for this purpose for example, a polymer-containing liquid can be used, which will wear directly on a cleaned side of the stone layer 100 before the gluing process.
- the application can by brush, cloth or ma shinell z. B. at room temperature and increased pressure Anpress.
- Such a barrier layer can be provided in various embodiments of reinforcing 1, 2 or insulating elements 1, 2.
